Raisin peels are edible, but they should be cleaned before consumption. Uncleaned peels may have pesticide residues or parasitic eggs and other harmful substances on the surface, which may cause gastrointestinal discomfort, such as abdominal pain, diarrhea, vomiting and other symptoms after consumption. Raisin peel has certain nutritional value, such as anthocyanins and various amino acids, vitamins, minerals and other substances, which can supplement the trace elements required by the human body and have certain benefits to the human body. Among them, anthocyanins have a natural antioxidant effect and are widely used in skin care products in recent years for their beauty benefits. In addition, the vitamins contained in raisin peel, such as vitamin A, help maintain healthy eyesight. Raisin peels contain a certain amount of tannic acid, which may cause gastrointestinal discomfort when consumed in excess, so moderate consumption is sufficient. Some people consider the skin of raisins to be astringent, so they can also be peeled and eaten according to their personal preferences. In addition, considering that raisins contain certain sugar, diabetic patients need to reduce consumption, and raisins are cold in nature, people with weak gastrointestinal digestive function should also reduce consumption to avoid causing abdominal pain, diarrhea and other discomfort.
